the Difference Between a Node and a Miner......

[Donk1]

 Newbies often face challenges like differentiating between who a node is and who a miner is which if I may say most times it's often confusing without the right research. So in this topic I will generally break down who and what is a node and a miner...

 In Bitcoin we have what is called a Blockchain and for those who don't know what a blockchain is, basically it's a global digital ledger that keeps records of every transaction ever made in the entire Bitcoin history.to ensure the safety of the blockchain so that it remains accurate and updated without any third party involved, the need of the Nodes and miners are generally required While they may both have similar task, still they have different responsibilities.
Why the confusion: I believe the reasons is because both the miners and nodes deal with bitcoin transactions ,and also they both runs on computers which are connected to the Blockchain network .basically true talk back then Satoshi nakamoto made them both as the Same thing which they where in the original software so that folks who run nodes can also get the opportunity to mine ,but right now their roles have been splinted....https://www.bitcoinmagazinepro.com/blog/complete-guide-to-bitcoin-nodes-and-how-they-work/?hl=en-GB

Node: The Network Guardians

 A node is a computer while those who control the computer are called node operators. That said nodes are connected to the Blockchain network .and as we all know their jobs are to verify and ensure every transaction's records are kept.
Duties of the Nodes....
1)Full nodes often hold the entire history of the network by downloading a copy of the Blockchain....

2)They serve as the checkers of transactions whereby when a person sends Bitcoin, the nodes often check to verify that the person sending has the amount of money they want to spend. If they don't the node will immediately reject it considering it as a scam attempt.....

3)Nodes often communicate with themselves by sharing new transactions across the Bitcoin network....

4) nodes have a unique power and authority, whereby if miners try to cheat in any way they will be totally ignored by the nodes.....


Miner: The Block Builders

 A miner can often be considered a node but with extra, more demanding duties. Basically their jobs are to arrange/organise new transactions into blocks and then ensure they are added to the Blockchain ledger....

Duties of the miners.....
1)Miners make use of powerful computers to solve confusing or let me say complex math puzzles which are called mining, adding new pages to the transaction history.

2)Miners compete with themselves just to solve a complex puzzle and the first miner to completely solve it gets to add a new block to the Blockchain.

3)For every new block added they get a reward, which are often new coins like Bitcoin and transaction fees.....

Overall as a newbie for you not to get confused you should never call a miner a node They might often deal with transactions, but then each has its unique responsibility which makes them very valuable to the Bitcoin Blockchain technology. That's all hope this was helpful.....

I think you’re explanation was ok that I don’t you needed to add this that newbies shouldn’t be call a miner a node, it’s not all wrong because a miner must be running a node or be connected to a node to get full information about the blockchain and most of the time this miners run their own full nodes and do not connect to any node, so a miner can definitely be a node but a node cannot always be a miner.

You made a few points clear, small fix.

1. Node are not mainly computers, they are software that runs in a computer. A computer isn't simply considered a node, node runs in a computer or device, it must be connected to the blockchain before considered a node.

2. Node checks if the UTXOs is valid or invalid, whether it has been spent before, nodes don't track your balance.

All node must obey the consensus rules, whatever is against will be considered invalid and rejected.

What does a Bitcoin node do?
Why is mining important?

A node has three jobs:

    Follow the rules
    Share information
    Keep a copy of confirmed transactions

Bitcoin miners compete with each other through their computational power and solve puzzles to find new Bitcoin blocks, and confirm transactions, add them into that new found block. From that Bitcoin miner's node, it will be relayed to other Bitcoin nodes, and nodes have to check block information, transaction information before finalizing it on the blockchain.

Bitcoin miners with mining hashrate also contribute to Bitcoin network security as with more network total hashrate, it's harder to have enough 51% hashrate for doing 51% attacks. You can understand more about it with the following thread.

In most cases I usually prefer to put it out as if you are connected directly to the network more like an anchor then you are running a node. So basically all miners are nodes though it's kinda debatable on a technical scale what actually differentiates them is if they are creating blocks and confirming transactions or they are just acting as a storage for the public ledger.

Well as for the cheating part, if you try to cheat with a transaction it won't really fit in the Merkel tree and because of that other nodes can't sync and accept it.

..., it must be connected to the blockchain before considered a node.

(Below I'm talking about Bitcoin nodes.)
That's some wording nonsense. Care to explain how a node "connects" to the blockchain?

A node connects to other nodes. They exchange and propagate validated transactions and blocks. Every node builds a local full or partial copy of the blockchain and maintains its local copy during operation. Nodes can ask other nodes for blockchain or transaction data they don't yet have, e.g. during an initial blockchain download or to complete missing parts of the blockchain to reach the current chain tip, e.g. when a node was offline for some time.

2. Node checks if the UTXOs is valid or invalid, whether it has been spent before, nodes don't track your balance.

Every node has to maintain the current UTXO set, which are the only chunks of coins that are valid to be spent. Bitcoin transaction model is NOT balance based, it's based on Unspent Transaction (TX) Outputs. Any UTXO which is spent as input in a transaction is spent in full and thus erased from UTXO set. If you want to spend only parts of it, you return the rest as change back into your own wallet (ignoring transaction fees for the moment), commonly. It's important to understand the Bitcoin transaction model.

.....

Nodes are connected directly to other nodes like @Cricktor stated. The connected nodes forms a giant distributed network which is peer-2-peer with each other. Each node keeps its own copy of the ledger. When connected to a node, we are simply downloading and syncing that file from your peer nodes.

I’m getting something from here and hope I’m clear on it so, let me just put it simply,

All miners run a node or are nodes but not all nodes are miners.

I hope that’s how it goes since, miners would have to create these blocks and verify transactions, making them the first phase in maintaining the integrity of the network while, the nodes uphold it.
